To aZZ whom z't may concern.- y

Be it known that I, EUGENE MOREAU, a citizen of the Republic of France,residing at Ihiladelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inMining- Machines; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to machines for linining coal, andmore particularlyto those which have revolving angers to penetrate the coal, and also tocut horizontal or vertical channels in the same, to separate it andextract it in portions from'the surrounding mass.

The object of my invention is to improve the construction of machines ofthis kind, lessen their weight, and diminish the coefficient-offriction, protect the mechanism fromV injury, and facilitate theiroperation.

With these objects inview my invention consists, essentially, in ahorizontal guide mounted on a standard tov support theoperative parts ofthe machine and guide them in boring or channeling; furthermore, inthecombination, with the driving mechanism, of automatic mechanism forcausing the auger toV progress in its work in. boring or to channelhorizontally or vertically', furthermore, in an improved construction ofthe auger-driving mechanism; furthermore, in aco'nstruction of thebearing of the auger-supporting part which will greatly diminish thefriction .and wear of such bearing; furthermore,l in an iml proved andmore compact assemblage of the different elements of the machine andtheir inolosure in a box or housing to protect them from injury by dustor blows; furthermore, in

a construetionof theauger itself whereby its removal or attachmentmay befacilitated; furthermore, in a construction of the auger whereby theknives may be attached to the helices in a manner best adapted tosimplify the manufacture of these knives, and, finally, in certain noveldetails of construction. l

In the'accompanyingdrawings, which forni a part of this specification,and in which-like. letters of reference 4indicate corresponding parts,

.ing spindle.

B represents a standard consisting ofa xied portion, b, having a claw onthe outer end, a fixed screw-nut, b', at its other end, and anintermediate sleeve, b2, provided with collars or clamp-rings b3, and ofa movable portion or screw, b4, having a claw on its outer end andbearing a hand-wheel, b5, by which it can be turned in the nut tolengthen or shorten the Standard. The screw-nut b is preferably splitand provided with a,bolt by means of which sufficient pressure may beexerted upon the screw to hold it in place when desired.

The horizontal guide Ais slung or swung to the standard by means of armsC, which are attached to the top and bottom plates a2 at c c', and arepivoted to the standard upon its sleeve by a bolt passing through aboss, C2, integral with the upper collar or clamp-ring lof' the sleeve.A heelpiece, a3, on the under plate a2 rests against the lower part ofthe sleeve b2. The sleeve can vbe secured at any height on the standardby means of the clamprings b3. It will be obvious that by the attachmentof the guide tuo the standard this can be swung laterally on thestandard orbe raised vertically on the same.

Between the sides of the horizontal guide is the operating mechanism ofthe machine, and this is contained in a box or housing which serves toprotect it from injury by dust or by blows. D designates this box orhousing, and it is composed, preferably, of two castings held togetherby bolts. The box is retained in the guide A by longitudinal flanges dat its upperand `lower margins, which are planed to work smoothly uponthe edges of the sides a 0f the horizontal guide. A tightening orlocking device, d d', of any suitable construction, holds the hox andthe operating mechanism firmly in position at any desired point on theguide. The upper part of the box is provided with a removable cover toenable examination of the internal parts of t-he machine and facilitatetheir lubrication.

As before remarked, the box contains the operating mechanism of themachine, and this consists of two groups-one, E, for driving the auger,and one, F, for guiding it--causing it to progress longitudinally orpenetrate, or to cut horizontally or vertically-that is to say,laterally or up and down.

Referring to the driving group, e designates a inain shaft, havingcrank-wheels e fixed at each end and passing through bosses e2, boredout to receive it and located immediately under the cover. Vithin thebox and fixed upon the shaft e is a bevetwheel, e3, which engages withanother bevelwheel, et, fixed upon the upper end of a counter-shaft, e5,to the lower end of which is fixed another bevel-Wheel, e, which mesheswith a further bevel-wheel, e7, fixed upon a shaft or revolving spindle,g, belonging to the auger portion G of the machine.

Referring to the guiding group, on the spindle g is a worm, f, whichengages the teeth of a gear-wheel, f, which gear-wheel is the first of atrain ending at the shaftf. This shaft carries a chain or cable gear,f3, connected with it by means 0f a friction-clutch,f, operated by ahand-wheel, f5. A'warp chain or cable, f, runs at one end through thechain gear, and is secured at the other end either at the upper andouter extremity of the guide A, as shown in Fig. 1, or at any otherplace convenient for the desired movement of'the auger.

It will be clear that as the crank-wheels e are turned rotary motionwill be imparted through the intermediate gear to the spindle g, andthat this in turn will give motion to the shaft f2 through theintermediate gear, causing this, when the warp-chain is properly held,to wind and pull upon it.

The revolving spindle g is held at its rear end, where it is alsoprovided with thrust-col` lars in bearings bored out to receive it in abracket, g', at the rear of the box, and at its front end is held in astationary spindle, g2, which is fitted to and runs through the forwardpart of the box and through a bracket, g3, a nut, g4, holding it firmlyin position. A4 part of the stationary spindle g2 projects considerablybeyond the front end of the box, and this part has the shape of anelongated cone in order to serve as a bearing for a tapering sleeve, g5,which revolves upon it. This tapering sleeve g5 is fastened to thespindleg by means ofa key, 06, which fits into a slot cnt through theend of each. To hold the key in place and thus keep the sleeve fixed tothe spindle, a nut, gl, is screwed on the end of the spindle g againstthe key, and to prevent the assembled nut, sleeve, shaft, and key fromcoming apart, and also to form a tight joint, so that oil fed to theinner part of the tapering sleeve g5, as hereinafter described, cannotescape, but will be led from the tapering sleeve g5 upon the revolvingspindleg through a spiral groove, g8, a cap, g, is screwed upon the endof the tapering sleeve.

The auger proper is designated by the letter G. It is so turned on itsinterior as to tit the outside of the tapering sleeve, and is held inplace upon this sleeve by means of a hinged bolt, gl". The auger hasregular helices g, and to these helices are riveted the knives y.

In a tapering auger the angle of the helix with the axis varies from endto end, provided the thread of the screw remains constant. Therefore aform of knife suitable for the rear end of the auger could not be of theproper shape for the outer end if the helices were of a uniform patternthroughout its whole length.

In order to use only one standard knife, the difference in the angle ofthe helix at each point where a knife or cutter is attached must becorrected by shaping the helix at that point according to the variation.To this end a boss, g, is provided at each point where a knife or cutteris to be riveted, and the face of each IOC) helices at the point offastening of each knife as follows: The standard B is first or cutterpermits the use 0f only one pattern of these knives or cutters, and thusgreatly simplifies the manufacture of these knives or cutters.

` The auger portion of the machine is properly supplied with oil at thecircular space g14 between the rear end of the tapering sleeve and.

the stationary spindle, and the oil is fed forward by the movement ofthe sleeve on the stationary spindle between it and thesupporting-spindle along a spiral groove, g8, into the cap, whence itpasses .back ward along the revolving spindle.

The operation of my coal-cutting machine is placed in position at theproper distance from a bank of coal, as shown in Figs. 2.and 3, and thewarp chain or cable f6, which engages the vchain gear f5, is fastened atthe end of the guide A say on a ring there. Thebox D is left/free tomove upon the horizontal guide by release of the tightening or leasesthe pressure of retaining device, holding the box Dinfplace. Thefriction-clutch fL is made to act by means of the hand-wheel f5, andthen the operator turns the crank or cranks'e. As'the` auger rotates,the chain chain or cable f, thus forcing the mechanism and the augerforward and causing the auger to penetrate the bank, the dbris resultingfrom the penetration being fed out by the action of the helices. Afterthe auger has been allowed Ito bore nearly its entire length theYmotion'oi' the'crank e is stopped, and the box is fixed in position bymeans of the tightening or locking device d. The warp chain or cable isthen detached from the end of the horizontal guide, i's`"passed around apulley on the box, and is attached to any suitable point adjacent to themachine, either to a wall of the bank or to a post.7 If the crank be nowagain set in motion, the movement of the machine will be one of rotationuponV the axis of the standard B, the-drawing upon the warp-chain i 5 5f by means of the chain gear fal'effecting this result. Y

It is evident that by simply attaching the chain to a point on the sideof the coal-cutter opposite to 'that at which it has just been attachedthe movement of the machine may be reversed; hence the movement oftranslation of the machine is always toward the point to which the fixedend of the Warp-chain is secured. l

If it be desired to cut'avertical channel, the

. warp-chain should be fastened to the roof above the outer end of thehorizontal guide,

locking device d', which re-V ofthe clampor other forml gear pulls uponthe warp and the auger would then rise, describing a vertical circularchannel having the axis of the boss c2 for acenter..

It isV clear that with the warp-chain and chain gear theauger can bemade to bore the coal, and also to channel it vertically or laterally,simply `by guiding'the saidwarp-cliain and attaching its fixed endaccording to thev work to loe done. l

It will be apparent that the chain feed will be equally effectiveshould' the machine be placed upon a guiding device other than thehorizontal guide A and the standard B, and I with either of theseparticular parts.

All the gearing which is lused to transmit the .motion of the cranks tothe auger and also to the warp-chain being entirely inclosed, the dustof the coal cannot enter the bearings and interfere with thelubrication; and, furthermore, by being so incl'osed the mechanism isperfectly protected from vblowsy and other causes of injury.

Having thus fully described my invention,
